How to choose the seeds of Gentiana? What are the methods of raising seedlings?

Gentiana, also known as gentian, the whole grass can be used in medicine, is one of China's traditional Chinese medicine. It has the effect of clearing heat and detoxification, cooling blood and promoting dampness. It is often used to treat cold, inflammation of tonsil and throat, irregular menstruation, abnormal leucorrhea and so on. The medicinal value is very high, and there are many farmers planting it. So how to choose the seeds of Gentiana? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to select the seeds of Gentiana?

The seeds of Rabdosia angustifolia are relatively small, and healthy and full seeds should be selected when planting, and higher temperature, humidity and light conditions are needed during germination, so in order to improve the germination rate, soaking seeds in warm water before sowing is generally carried out to promote germination.

Of course, if the area with suitable temperature does not need to promote germination, it can sprout in about a week at a temperature of about 25 degrees. After emergence, the seedlings grow in an environment that likes weak light and is afraid of strong light, so if the light is too strong, it is necessary to do a good job in shading and sun-shielding maturity. at the same time, strengthen seedling stage management. Keep the soil moist and promote the growth of seedlings.

Second, what are the seedling raising methods of Gentiana?

1. Land selection and preparation

Gentiana is a wild plant, which has strong adaptability to the environment and lax requirements on soil, but for yield and income, it is best to choose land with good drainage, deep soil layer and loose and fertile soil. When planting on the hillside and forest edge, in the winter of the year before planting, we should plough the land, clean up the residual plants of stones and weeds in the field, and apply an appropriate amount of farm manure as base fertilizer according to the state of soil fertility. in addition, the same is true of planting under the forest or intercropping in the orchard.

2. Methods of reproduction

The propagation methods of Herba Euphorbiae include seedling transplanting, seed direct seeding, root division propagation, cutting propagation and so on. Before transplanting and sowing, the seeds should first be dried or germinated, and then sowed on the seedbed, generally 1.5-2 kg per mu, covered with a layer of shallow soil. After emergence, do a good job of seedling management, transplant when the seedlings grow to 5 leaves, wet the seedlings when transplanting, in order to avoid root damage, and then open holes in the planting ground to plant. Direct seeding is suitable for pure planting or orchard and forest intercropping, opening holes in the ground according to the row spacing of 20cm × 15cm, sowing 6-8 grains in each hole, covering a layer of fertile soil after sowing, watering to keep the soil moist, and time seedlings and fixed seedlings after emergence.

3. Field management

Seedling transplanting 7-10 days after survival, we should inspect the garden in time, find that the unsurvived plants should be pulled out, and replenish the seedlings in time, in addition, the same is true of direct seeding. After half a month of seedling replenishment, it is necessary to timely plough weeds and promote seedling growth, combined with 500-600 kg of rotten human feces per mu to speed up seedling growth. In the future, according to the growth status of seedlings and weeds, timely ploughing and weeding should be carried out. If the weed damage is serious, fertilizer should be applied in time after weeding, so as to avoid poor plant growth and affect the yield and quality. In order to save nutrients in the later stage, for the planting with no seeds, the buds should be removed in time to concentrate nutrients for rhizome growth in August, so as to promote rhizome yield and increase income.

4. Collection and processing

The collection and processing of Gentiana differs due to different ways of utilization. For seed use, during the seed maturity period from October to November, the harvested fruits are dried and stored for storage. For medicinal use, it is generally harvested in autumn, and after harvest, the whole plant is dried for sale or storage for medicinal use. For root-splitting propagation, the underground rhizomes were harvested in autumn and cut into stem segments with more than 3 sprouts for planting and propagation. For cuttage propagation, the aboveground stem was harvested from June to July, and before the flower bud differentiation, the aboveground stem was cut, the top tender part was removed, and the stem segment with 3 nodes was cut to raise seedlings or plant.

The above is the introduction of Gentiana, Gentiana is one of our more common medicinal materials, the market demand is large, want to plant Gentiana, we must master the above seedling methods, hope that the above content can be helpful to growers.
